
Pull the rubber cover out of the fuel
tank.

Unscrew the retaining plate.

Remove the fuel tank.

Rinse out the fuel tank.

Refit and assemble the fuel tank.
If deposits accumulate in the pipelines, this
increases the flow resistance and the motor
load of the cold water high-pressure clean-
er becomes too great.
 DANGER
Risk of explosion due to combustible gas-
es! Smoking strictly prohibited during de-
calcification. Ensure proper ventilation.

DANGER
Risk of burns injury on account of acid!
Wear protective glasses and protective
gloves.

Procedure:
According to statutory requirements, only
tested and approved boiler decrusting
agents may be used.
– RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.
– RM 101 (Order No. 6.287-013) dis-
solves the deposits that cannot be dis-
solved using RM 100.

Fill a 20 litre container with 15 l water.

Add one litre of boiler decrusting agent.

Connect the water hose directly to the
pump head of the cold water high-pres-
sure cleaner and hang the free end into
the container.

Place the spray lance connected to the
hot water generator in the container
without the nozzle.

Switch on the cold water high-pressure
cleaner as described in the manufactur-
er's operating instructions.

Open the hand-spray gun and do not
close it during the decalcification pro-
cess.

Switch the cold water high-pressure
cleaner off and allow it to stand for at
least 2 hours. The trigger gun must re-
main open.

Once this time has elapsed, pump out
the decrusting agent of the cold water
high-pressure cleaner and hot water
generator without spray lance and hand
spray gun.
ATTENTION
Risk of damage! Freezing water in the ap-
pliance can destroy parts of the appliance.
– Store the appliance in a heated room
during winter or empty it. During longer
breaks in operation, it is advisable to
pump in anti-frost agents into the appli-
ance.
– If it is not possible to store frost free,
shut down device.

Drain water:

Unscrew the high-pressure hoses from
the high-pressure input and high-pres-
sure outlet.

Flush appliance with anti-freeze agent:
Note: Observe handling instructions of the
anti-freeze agent manufacturer.

Rinse the cold water high-pressure
cleaner and hot water generator (burner
off) thoroughly with a commercially
available anti-frost agent.
A certain corrosion protection is achieved
with this as well.

DANGER
Risk of injury by inadvertent start-up of ap-
pliance and electric shock. Prior to all work
on the appliance, switch off the appliance
and pull the power plug.
